Decoding string xml in .net

Question

Hy,

i want to decode a string which contain xml data in .net but that string was encoded in java

System.Text.UTF8Encoding encoder = new System.Text.UTF8Encoding();
System.Text.Decoder utf8Decode = encoder.GetDecoder();
byte[] todecode_byte = Convert.FromBase64String(data);
int charCount = utf8Decode.GetCharCount(todecode_byte, 0, todecode_byte.Length);
char[] decoded_char = new char[charCount];
utf8Decode.GetChars(todecode_byte, 0, todecode_byte.Length, decoded_char, 0);
result = new String(decoded_char);
return result;

i have written that code but it throw error. Thanks in Advance.

For the love of all that is binary please provide the error. — ChaosPandion

The input is not a valid Base-64 string as it contains a non-base 64 character, more than two padding characters, or a non-white space character among the padding characters. — jats

@jats: Then that sounds like it's not base64 to start with - what made you think it was? — Jon Skeet

Assuming it really is UTF-8 which is then base64-encoded, you should just be able to write:

byte[] binary = Convert.FromBase64String(data);
string text = Encoding.UTF8.GetString(binary);

However, it sounds like it wasn't base64-encoded to start with - if you've already got it as text, you should be able to use it without any extra work.
